Many tumors are hierarchically organized with a minority cell population that has stem-like properties and enhanced ability to initiate tumorigenesis and drive therapeutic relapse. These cancer stem cells (CSCs) are typically identified by complex combinations of cell-surface markers that differ among tumor types. Here, we developed a flexible(More)
Studies showed that specific probiotics might provide therapeutic benefits in inflammatory bowel disease. However, a rigorous screening of new probiotics is needed to study possible adverse interactions with the host, particularly when intended for administration to individuals with certain health risks. In this context, the objective of this study was to(More)
Dendritic cells (DC) capture immune complexes (IC) via Fc receptors for immunoglobulin G FcgammaRII and elicit antigen presentation and protective antitumoral immune response in mice. Two protocols are commonly used to differentiate human monocyte-derived DC in vitro. They associate granulocyte macrophage-colony stimulating factor (CM-CSF) with interleukin(More)
Chronic ingestion of environmental heavy metals such as lead (Pb) and cadmium (Cd) causes various well-documented pathologies in specific target organs following their intestinal absorption and subsequent accumulation. However, little is known about the direct impact of the non-absorbed heavy metals on the small intestine and the colon homeostasis. The aim(More)
Although the heavy metals cadmium (Cd) and lead (Pb) are known environmental health concerns, their long-term impacts on gut ecology and susceptibility to gastrointestinal autoimmune diseases have not been extensively investigated. We sought to determine whether subchronic oral exposure to Cd or Pb is a risk factor for the development and progression of(More)
Dendritic cells (DCs) capture immune complexes (ICs) via Fc receptors for immunoglob-ulin G (Fc␥R)II and elicit antigen presentation and protective antitumoral immune response in mice. Two protocols are commonly used to differentiate human monocyte-derived DCs in vitro. They associate granulocyte macrophage-colony stimulating factor with interleukin (IL)-4(More)
Gut microbiota plays a key role in the maintenance of homeostasis and host physiology, comprising development, metabolism, and immunity. Profiling the composition and the gastrointestinal microbiome with a reliable methodology is of substantial interest to yield new insights into the pathogenesis of many diseases as well as defining new prophylactic and(More)
